a UV/Vis spectra of PMA reduction through the oxidation of LC biomass, lignin, hemicellulose, and cellulose at 60 °C for 8 h. b Calculated activation energies for PMA reduction by LC biomass, lignin, hemicellulose, and cellulose according to Arrhenius plots. c Production of vanillin and acetovanillone from LC biomass, lignin, hemicellulose, and cellulose oxidation. d Schematic illustration of electron extraction and production of value-added chemicals from LC biomass via the selective depolymerization. e LSV curves of only 0.5 M H2SO4, pristine PMA3−, reduced PMA5− by LC biomass, and reduced PMA5− by lignin. f CA curves of reduced PMA5− by LC biomass and lignin at 0.8 V vs. RHE.
